The frame 10 carries a solid metal bottom H which covers the entire lower side thereof and is substantially parallel to the separating devices above it'so that the meats and such hulls as'pass' through the perforations and opening 0 will travel downwardly and be deliveredat the lower'end into suitable conveying or other means to receive it (not shown). The hullstailing off the lower edge of the plate G are also delivered to f suitable conveying means (not shown),

The operation of the device and the method of separating hulls from the mixture of hulls andmeats will be described. 7 The mixture ofhulls and meats is discharged from the cotton seed or other huller into thethopper 13 and from there delivered onto the upper end of the screen A. As theframe r and the materials thereon are agitated the kernels or meats of the seed being the heavier will-work to the bottom of the mixture while the hulls, being the lighter, will 7 remain .on top of. the meats. By the time the mixture ireaches'the opening 0 it has thus been stratifiedinto two layers, the

lower layer consisting mostly of meats and the upper layer consistingmostly of hulls.

" The agitation of the frame also causes the 'finer meats and some hulls to pass through a the screen Aonto the bottom H while the mixture is travelingdown the screen to the opening 0.] The smaller meats are thus first sep'a'ratedout by the screen A.

' As illustrated inFig. 3 when the Stratified hulls and meats reach the lower end of the screen A, a part or all of the upper layer of hulls is skimmed off by the edge 19 of the blade'B and thela'rge meats'and some hulls pass throughtheaopening 0 onto the bottom H. The block 21 is not essential to the operationof the separating mechanism but I have found it to be useful as it retards the stream of hulls and meats and allows such kernels or meats which have otfound the 1 bottom of the mixture to further settle so 7 that they will pass out through the opening O under'the edge 19. The hulls pass over the upper edge of the block 21 and continue 7 downwardly over the lower.- end of the blade B and screen Oto the pockets or depressions D and B. Any small meats which have passed over the block 21 with the-hulls will *pass through the perforations in the part of thebladeB belowthe block 21 or through the perforationsin theplate C. Any large -meats which pass over "the block 21 will be caught in the depressions D and E and pass throughsthe perforations in the} bottoms thereof and'some but not many hulls w1ll also pass through these perforations.

Separatmg mechanisms formerly used were provided'with large perforations at the upper end for large meats and smaller perforations in subsequent parts for smaller. ,meats but in the 'present construction the smaller meats and fine particles 'of hulls are separated out first and the larger meats are separated later. thumb screws 18 the amount of hulls going through the openingQ may" be regulated and 'it is therefore unnecessary to; change any of the separating screens to control exactly the amountjof hulls mixed with the meats and the ammonia and protein content l WVhile I have ofthe meal derived when themeats have passed through thepress.

The methodiof separating {115111111 from the meats and the mechanism for accomplishing such a separation is adapted for the separation of cotton seedhullsfrom'the .vent-ion in detail, I do not wish to be limited to the exact form of construction shown, as
